If you’re venturing deeper into the world of vaping, you’ve probably come across terms like RDA, RTA, and sub-ohm tanks. While all three are types of vape tanks, each has unique characteristics, advantages, and use cases. Whether you’re chasing clouds, dialing in the perfect flavor, or just want a hassle-free vape setup, understanding these differences can help you find the tank that suits your style.
Sub-Ohm Tanks
Sub-ohm tanks are the most popular type of vape tank for everyday users. These tanks use prebuilt coil heads, making them a plug-and-play option: perfect for vapers who want big clouds and strong flavor without the complexity of building coils.
- Resistance: Below 1 ohm (hence “sub-ohm”)
- Draw Style: Direct-to-lung (DTL)
- Best For: Cloud chasers and vapers who want strong flavor with minimal effort
- Setup Time: Minimal: just screw in a coil, prime it, and fill the tank
Modern sub-ohm tanks often use mesh coils, which offer excellent flavor and longer lifespan compared to traditional wire coils. They usually feature top-fill systems and adjustable airflow for a customized experience.
Pros:
- Easy to use
- No coil building required
- Widely available and beginner-friendly
Cons:
- Replacement coils can be pricey
- Less customization compared to rebuildable options
RDA (Rebuildable Dripping Atomizer)
RDA stands for Rebuildable Dripping Atomizer. This type of tank, or more accurately, atomizer, does not hold vape juice like a traditional tank. Instead, you drip e-liquid directly onto the coil and wick every few puffs.
- Draw Style: Can be DTL or MTL, depending on build
- Best For: Flavor purists, cloud chasers, and coil-building enthusiasts
- Setup Time: High—requires building and wicking coils manually
RDAs offer unmatched flavor and vapor production because there’s no chimney or tank section for flavor to degrade in. They also allow advanced users to experiment with different wire types, coil builds, and wicking techniques.
Pros:
- Outstanding flavor
- Easy to swap or adjust coils
- Perfect for testing new e-liquids
Cons:
- Requires frequent dripping
- Not ideal for on-the-go vaping
- Steeper learning curve
Some users pair RDAs with squonk mods, which feed e-liquid from a bottom bottle, eliminating the need to drip constantly.
RTA (Rebuildable Tank Atomizer)
RTA stands for Rebuildable Tank Atomizer. It’s the middle ground between RDAs and sub-ohm tanks. Like RDAs, RTAs require you to build your own coils, but they also feature a built-in e-liquid reservoir like a traditional tank.
- Draw Style: Often DTL, but some MTL RTAs exist
- Best For: Experienced vapers who want full control with the convenience of a tank
- Setup Time: Moderate, coil building plus tank maintenance
RTAs can deliver fantastic flavor when wicked correctly, but they’re notorious for leaking issues if you don’t wick them just right. However, many modern RTAs now feature leak-resistant designs that make them easier to handle than older models.
Pros:
- Rebuildable with a tank for added convenience
- Great flavor and vapor when set up correctly
- Cheaper in the long run due to reusable coils
Cons:
- More complex to build and wick
- Potential for leaking if not wicked properly
